Theres just no telling these days. They may have thought it was the core and it was the fill port or the condenser fitting. Or the compressor seal. Maybe they did not evacuate it and clean the orfice or did not load the correct oil charge ratio. But if its the compressor it either was already leaking or no oil or it dry ran and fouled the orfice out or even the accumulator.

You never know what level of experience your getting a lot of the time.

Sorry to hear about your troubles

 

Well, the compressor is in fact shot. They assured me that the evaporator core being bad from the factory and being replaced at 6000 miles didnt have anything to do with it, but I am still not entirely sold. It just seems like a crock to me that I am laying out 1400 dollars on a compressor when the system was flawed from the factory. I am no mechanic, but I have never had a compressor fail this early. The service writer told me that they have the problem frequently in the 450 and 550 because of extended idle time. Does this make any sense to you? Can you explain it to me?

 

That sounds like a line to me. If its common then there would be a TSB or recall. I think that they may not have charged it right. Or then compressor was damaged already from the loss of oil. Or high discharge head or NPSHA was not at the NPSHR for the unit due to a fouled orfice. I would ask if they are replacing the orfice and purging the condensor. I would also ask if they are going to run it on a dryer or put one in it.

i can provide additional AC details as needed, but not right now - shhhh ibatwork

 

They did flush the system as well as replace the dryer. I did consult another mechanic, and he said that it is not likely that the issues were related. Thanks for the input.

 

Hmmm
Lets see loss of freon and oil. starved compressor . metal fatigue fouled orfice higher discharge head, lower suction head. Compressor cycling due to low pressure sensor cut off.

So if they flushed it but never pulled the orfice and if they supplied the correct freon to oil ratio. It would still fail the compressor on cycles.

I bet they never pulled the orfice and there was compressor wear to begin with that fouled the orfice.

Best of luck sounds like you have help to figured it out.

 

I noticed that my AC was not cooling on my 2011 F250 and brought it to my Ford dealer for a check. Just got a call that my evaporator needs to be replaced... Truck had ~42,000 miles when the cooling was lost, but couldn't get to dealer until just over 44,000 miles. Warranty expires on the evaporator at 36,000 miles....ugh! Over $1600 repair....UGH!

Has anyone else had this issue? Quality evaporators shouldn't expire this soon.

Called Ford - Their reply "Sorry for the issue, but your vehicle is out of warranty."

 

In the troops, I'm glad you're here for us m-chan!

Dharper, your trucks a mess man, sheesh...

 

Got to assist in one of these two weeks ago. The gentleman helping my buddy do it is a Ford tech in the gas garage. Said this was the 10th one he has done. Gave me the signs to look for. Said keep an eye out for a shiny frame rail right behind passenger front tire.

 

I had 2 issues with my 2011. First was at about 6k, compressor (I was told) literally fell apart from the backside. Don't quite know what that means, but its what the service advisor said.

Next, happed at about 45k. The blower went out. $500 later the AC worked again.

 

Biggest issues are the evsporator cores are splitting like the radiators are.

 

So this afternoon I was backing down my driveway and all of a sudden I here a really loud hissing. I get out to check the tire for a leak,no leak but a big cloud of fog. I pull back up to the house and open the hood. Something with the A/C exploded green die everywhere. Only 15k miles 2011

 

Wow, this sounds like something you need to get in front of your dealership, Richman1891. Be sure to let us know what you find out. I'll check on this thread for your updates.

Just back from the dealership. One of my fittings came loose,so all the freon leaked out. It was under two bills, so I guess not to bad.

 

Glad to hear they got you all fixed up, Richman1891. Thanks for sharing your results with us.

I've never heard of anyone that knows what they're doing flushing the A/C system with the orifice tube in or the dryer still hooked up and not replacing the dryer afterwards.
